One national market beats a map of gaming boards
Sports contracts need rules. But many of the parties asking the Court for state control also profit from the licensed sportsbooks the exchanges compete with.
Look at who is lining up against Kalshi at the Supreme Court. The docket lists briefs from gaming regulators, legislators from gaming states, the American Gaming Association, the Casino Association of New Jersey and, as of Thursday, the National Football League. These are serious parties with serious arguments. Many of them also make money from the licensed sportsbook system that prediction markets compete with.
An exchange is a different animal from a sportsbook. A sportsbook sets the line and does well when its customers lose. An exchange matches buyers with sellers, charges a fee, and keeps a record of every trade that a regulator can audit. If the worry is someone trading on an injury report before it is public, one central order book under one federal supervisor is a better place to catch it than a patchwork of state-licensed books.
The Third Circuit read the statute and concluded in April that these contracts, traded on a federally designated exchange, belong to the CFTC. Two other circuits disagree, which is exactly why the Court should settle it. But the answer should not turn on whether a contract feels like gambling to the people who license gambling. Election contracts felt that way to the CFTC itself, until a federal court ruled for Kalshi in 2024.
The league's own brief is more candid than the headlines about it. It says that if the Court sides with the Third Circuit, the NFL will press the CFTC, the exchanges and Congress for stronger integrity and consumer protections before the 2027 season. That is the right fight. Age limits, banned-bettor lists and data-sharing with leagues can be written once, federally, and bind every venue in the country.
The alternative is a state-by-state map, each state with its own licence fees and its own incumbents to protect. Baseball and hockey have already signed deals with prediction markets; football has chosen the states. Customers are better served by one set of rules, written in the open and enforced nationally, than by whichever lobby is strongest in each capital.
